Getting Your VO2 Max. Estimate
Before you can view your VO2 max. estimate, you must put on the heart rate monitor, install the power meter,
and pair them with your device (Pairing Your Wireless Sensors, page 40). If your device was packaged with a
heart rate monitor, the device and sensor are already paired. For the most accurate estimate, complete the user
profile setup (Setting Up Your User Profile, page 46), and set your maximum heart rate (Setting Your Heart Rate
Zones, page 37).
NOTE: The estimate may seem inaccurate at first. The device requires a few rides to learn about your cycling
performance.
1 Ride at a steady, high intensity for at least 20 minutes.
2 After your ride, select Save Ride.
3 Select Menu > My Stats > Training Status > VO2 Max..
Your VO2 max. estimate appears as a number and position on the color gauge.

Tips for Cycling VO2 Max. Estimates
The success and accuracy of the VO2 max. calculation improves when your ride is a sustained and moderately
hard effort, and where heart rate and power are not highly variable.
• Before your ride, check that your device, heart rate monitor, and power meter are functioning properly, paired,
and have good battery life.
• During your 20 minute ride, maintain your heart rate at greater than 70% of your maximum heart rate.
• During your 20 minute ride, maintain a fairly constant power output.
• Avoid rolling terrain.
• Avoid riding in groups where there is a lot of drafting.
